MEXICO CITY (AP) — Five non-editorial employees of a newspaper in northern Mexico were kidnapped but released within a few hours, the company said in an editorial posted on its website Friday. It complained there is a lack of security for news workers in the violence-plagued region around the city of Torreon.

The newspaper Siglo de Torreon, in the state of Coahuila, said abductors took two people who operated its online services, two employees of the advertising department and one administrative employee. It said the workers were released early Friday, but that for security reasons, it would not give any further details on the incident.
